School me on wiring

No, I never said they are stupid. I understand and have used them in other applications countless times.
I said that they are an unnecessary complication in the vast amount of cases when it comes to these cars.
The old saying was that some people have too many fingers on their hands. Meaning, they know how to do something, and so they do it everywhere they can whether it is needed or not.
I see people doing things to these cars that boggle my imagination sometimes. Taking a machine who's essence lies in its simplicity and functionality and heaping all sorts of things on top just because it seems like the thing to do.
I'm not an automotive "prude" by any stretch of the imagination. But, a lifetime of screwing with these things has proven to me time and time again, that the simplest machine is nearly always the best machine.
